Referring noW to the illustrative embodiment of my invention depicted inthe accompanying drawing, there is provided a normally upright inletcasing, generally designated 1, of double Wall construction. Casing 1includes an outer tubular member 2 and an inner tubular member 3. Tube 2is provided adjacent its lower end with an external flange 4 adapted toseat against the bottom wall 5 of an associated toilet tank, a sealinggasket 6 being interposed therebetween. Outer tube 2 extends through anopening in the tank wall 5, terminating in an externally threadednipple'7 for attachment to the usual supply line, not shown. Inletcasing 1 is secured in place in the tank by a nut 8 threaded on nipple 7and bearing against bottom Wall 5.

Casing 1 is elongated, comprising in the illustrated embodiment a hollowcylinder on which a float member 9 is guidingly supported for rising andfalling in the manner of float members 18 and 18 of my pendingapplication Serial No. 249,954 now Patent No. 3,144,875. Indeed, float 9can be like either of said floats, except that it is provided with acentral opening 10 at its upper end for projection of inlet casing 1therethrough. Float 9 has a circumferential opening 11 in its outer wall12, for entry of water into the water chamber portion 13, with air beingtrapped in the air chamber portion. 14. Chambers 13 and 14 are definedby the tubular inner wall 15, outer wall 12, and bottom and top walls 16and 17. The inner float wall slidingly receives casing 1 therethrough.

The inner tubular member 3 of inlet casing 1 provides a Water inletpassage and is arranged in concentric, spaced relation to the outermember 2. Member 3 terminates at its lower end in a lateral flange 18bearing against the inner Wall of tube 2 in sealing engagement therewithat a point spaced below the tank bottom wall 5. A similar llange 18 isprovided at the upper end of inner member 3, in sealing engagement withmember 2 at a point near its upper end.

At its upper end, inlet casing 1 supports an inlet control valve housingcomprising an enlarged body 19 having an externally threaded, downwardlyextending nipple 20 threaded into the internally threaded upper end ofouter member 2. A normally horizontal, annular valve seat 21 is providedin body 19. Seat 21 has a central inlet port 22 communicating with theinlet passage through casing 1, and a series of outlet passages 23around port 22 in spaced relation thereto. A main control valve, in theform of diaphragm 24 is positioned in body 19, to overly seat 21.Diaphragm 24 has a depending peripheral iiange 25 locked in place in acorresponding groove in body 19 by the centrally apertured back-upmember 26. For assembly, body 19 can be made in two, upper and lowerparts, joined adjacent member 26. Diaphragm 24 carries a tubular oricemember 27 having a pressure equalizing passage therethrough into apressure'chamber 28 between diaphragm 24 and the upper end of body 19. Ableed valve 29 is provided, having an O-ring seal 30 adapted to seatagainst the underside of the top wall of body 19'to close a bleedpassage 31 therethrough. A post 32 projects from bleed valve 29, throughpassage 31. Bleed valve 29 is provided with a central recess 33 in itsundersurface for receiving the jet of water through pressure equalizingmember 27, to assist in seating bleed valve I29 when iloat member 9rises.

In the illustrated embodiment, the bleed valve unseating means comprisesa member 34 having a clevis end 35 pivotally connected to an upstandinglug 36 on housing 19, as shown at 37. Member 34 extendsracross the upperend of housing 19, and is provided with an oblique cam surface 38 forcanting bleed valve post 32,

to crack open bleed valve 29. This relieves the pressure in chamber 28,causing valve 24 to move away from its seat 21, placing outlet passages23 in communication with inlet passage 22. The canting of bleed valve 29provides for easy opening .and closing of the valve, smoothly and withless surging. Member 34 is swung about its pivot 37 by float 9 through aconnecting link 38 provided at one end with a reduced neck 39 looselyreceived in the forked, hook shaped end 40 of member 34. At its oppositeend, link 38 is releasably clampedl in a resiliently yieldable,semicylindrical socket 41 carriedy on the side of float 9. The level ofWater in the tank, Whenfilled, is indicated at A, but this can be variedby moving link 38 lengthwise in socket 40. Member 34 is hollow, toenclose post 32, and seats on the top wall of housing 19 when oat 9drops.

The foregoing comprises the inlet section of my supply v valve assembly.f

A laterally extending arm 42y containing a water outlet, transferpassage 43 is provided with an upstanding sleeve 44 encircling the lowerpart of body 19, which can be of reduced di-ameter as shown. Arm 42 alsois provided with an internally shouldered, depending sleeve 45 engagingaround the upper end of tube 2, the arm 42 seating on said upper end asshown. The bottom wall 46 of arm 42 is spaced below the bottom wall ofbody 19, to provide an annular collector passage 47 from outletpassages23, into the main outlet or transfer passage 43.

Arm 42 provides atransfer section, from the inlet section previouslydescribed to the tank filling section described below.

The tank lling section comprises an'elongated tubular member 48 carriedby arm 42. To this end, arm 42 is provided with an upstanding sleeve 49encircling and supporting member 48 adjacent its upper end. Member 48 isof open mesh side wall form, comprising generally parallel threads 50Wound in one direction along its length,

the threads 50 crossing and being secured to generally v parallelthreads 51 wound in the opposite direction along the length of member48. Plastic material is preferred, whereby the mesh is resilientlyflexible, and member 48 is bonded or otherwise secured to sleeve 49.

A second tubular sleeve 52 extends upwardly from arm 42, in concentric,outwardly spaced relation about the upper end of member 48 and sleeve49, defining an annular connecting passage 53 communicating with themain filling passage 43 through arm 42 and with the interior of fillingmember 48 through its side wall adjacent its upper end. Sleeve 49 closesthe open mesh of member 48 for a portion -of its length adjacent itsupper end, conning delivery of water to the upper end of member 48.

An annular cap 54 has a skirt y55 secured about the upper end of sleeve52, and extends across the upper end of filling member 48 which abutsthe cap. Cap 54 also has a central opening 56 therethrough into theupper end rof tube 48. Member 48 is open at its opposite ends, and ispositioned with its lower end in closely spaced relation to the tankbottom wall 5.

A laterally projecting nipple 57 on arm 42 communicates with a passage53', formed by a pair of upright baiiies 54 extending from the bottom ofpassages 43 and 53 to the upper end of sleeve 49 in spaced apartrelation around sleeve 49 on opposite sides of nipple 57, Nipple 57 isadapted for connection to a bowl filling conduit, not shown, leading tothe usual overflow pipe, also not shown, the upper end of which is atlevel B, above water level A but below the upper end of sleeve 49.

The operation -of this embodiment of my invention is as follows. Uponushing the tank, the water level drops, causing oat member 9 to fall tothe position shown in FIG. 1. This pulls lever 34 down, canting bleedvalve post 32 and opening bleedy passage 31, as shown.j The supply linepressure thereupon lifts diaphragm valve 24, permitting water to owthrough inlet 22 across seat 21 and.

through passages 23, 43 and 53 to the tank filling member 48. I Thewater liows downwardly through member 48 by gravity alone, running downthe side wall of member 48 to a point closely adjacent the bottom wall 5of the tank. The open mesh, flexible construction of member 48 providesa smooth, quiet flow and delivery of Water to the interior of the tank,and the provision of gravity flow only substantially to the bottom ofthe tank eliminates turbulence and the noise associated with pressureflow. This is important, not only in noise reduction, but also becauseturbulence is believed, by some at least, to caus objecti-onablesweating.

As Ithe tank ll-s, the rising water level traps air in the upper portion14 of ilo-at 9, whereupon it rises on casing 1. This releases bleedvalve 29, which floats into bleed passage closing position, bein-g aidedby the water jetting through orifice member 27 against the bleed valveand into -recess 33 therein. It has been found, for example, that astream of water will shoot through the orifice to a hei-ght of about oneinch. IOnce .bleed passage 31 is closed, pressure in chamber 28 buildsup, causing diaphragm 24 to close and thereby shutting off the inflow ofwater. i

Water also tiows through passage S3' to fill the toilet bowl throughoutlet 57. Because of baffles 54', water cannot pass from passage 43 ltothe bowl filling -outlet 57 until it rises in passage 53 to the upperend of sleeve 49. Thus, a portion of the incoming water is diverted tothe bowl filling outlet 57, `for simultaneous filling of the tank andbowl.

The tank fill-ing passage through member 48 is at all times open toatmosphere through opening 56 in cap 54, which is above t-he siphonbreak level las determined by over-how level B. The same is true of theIbowl filling passage through outlet 57.` Consequently, should there bea drop in supply line pressure, producing back flow such as mightotherwise siphon lwater from either the tank or 4the bowl through thesupply assembly and into the supply line, the -cha-in is at once brokenby the air breakthrough opening 56. It is a particular feature of myinvention that this Siphon break is open to atmosphere at all times, isin both the tank land the lbowl filling lines, and contains no valves orother parts which could stick or otherwise fail t-o function. Therefore,back `siphoning cannot possibly occur.

Another particular feature of my invention is that arm 42 is swiveled onbody 19 and tube 1 of the inlet section. As a result, in-let casing 1,and indeed the entire inlet section, can be mounted in the tank withoutregard to the particular angular yposition of arm 42. Arm 42 then .issimply swung into the position desired for ease of connection of thebowl filling conduit (not shown) to nipple 57, and for locating the tankfilling section as desired.

Another feature of my invention is the mounting of valve housing 19 oninlet casing 1. Housing 19 simply threads int-o casing 1, whereby it canbe removed when desired. For example, upon installation housing 19 canbe unscrewed from casing 1, flushed out to remove any debris, and thenreplaced.

Also of significance is Ithe double wall inlet casing 1. The lower endof outer tulbe 2 is provided with laterally opening weep holes 58therethrough, below the tank bottom wall 5. Holes 58 communicate withthe annular chamber -59 which is defined by tubes 2 and 3 betweenflanges 18. Chamber 59 is completely isolated by tube 3 and flanges 18from 4the supply line connected to nipple 7, and from the supply passagethrough tube 3. Nut 8 is provided with a wall engaging skirt 60, spacedoutwardly from -tube 2 and provided with lateral passages 61therethrough communicating with weep holes 58. Therefore, should anyleak develop in the outer tube 2 of inlet casing 1, water entering theinlet `casing 1 from the tank will be confined -between tubes 2 and 3and will pass out through weep holes 58 and passages 61 withoutcontaminating the 4supply system. The number and size of passages 58 and61 are such as to quickly drain the chamber or passage 59.

A strainer 62 can be positioned in the nipple 20 of body 19, as shown.Strainer 62 is the same as that shown at 58 in my pending 'applicationSerial No. 116,859, -to which reference is made for details thereof.

A ow controlling pressure Iregulator 63 :also is provided, being mountedin the valve hofusing nipple 20. As shown in FIGS. 5-8, regulator 63comprises -a rigid first body member 64 having :a projecting centralboss 65 surrounded Iby an annular recess 66 on its upstream end. Member64 has an annular `side wall 67 extending beyond the base of boss 65,but terminating short of the outer end thereof. A series `of passages 68extend through member 64 around the boss 65 adjacent side wall 67.

A resiliently yieldable second body member 69, of rubber or the like,seats on side wall 67 against the upstream end of member 64. Member 69has a central passage 70 therethrough, and is frusto-conically recessedon its downstream side, as shown at 71.

In operation, water flows through passage 70, over the center boss 465and through passages 68 into the inlet port 22. If the `supply pressureincreases, the central portion of member 69 moves toward the boss 65 ofmember 64, thereby restricting the fluid passage between the members andmaintaining the desired rate of flow despite the increase in pressure.In -other words, a relatively even rate of flow is maintained throughthe pres-sure regulator, despite fluctuations in pressure.

Also, I provide a unique pressure equalizing orifice 27, in that theinlet end is provided with transverse slots 72, Aand is covered with acap 73 having a recess 74 receiving the slotted end of member 27. Recess74 is shallow enough, to leave the inner end portions of slots 72 openfor the ingress of water. The outer end 75 of cap 73 is conical, and thecap 73 projects llaterally a substantial distance beyond the member 27.Accordingly, water must move laterally inwardly through the slots 72,.and the cap 73 defiects any pieces of grit, or other debris such asmight clog the orifice through member 27 Memlber 27 extends throughdiaphragm 24, having a flange 76 seating against the inlet side thereof.

Accordingly, it is seen that my invention ful-ly accomplishes itsintended objects. Preferably, all of the parts are made of non-corrosivesynthetic lplastic: material, except forthe diaphragm tand gaskets,which can be of rubber, preferably also synthetic. While I havedisclosed and described in detail only one embodiment, and modificationof a part thereof, that has been done by way of illustration, -it beingintended that the scope of my invention be limited only as dened by theappended claims.
